Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of water surface cleaning equipment, specifically to a floating debris collection and storage device for an unmanned surface cleaning vessel. Background Technology
[0002] Unmanned surface cleaning vessels (USVs) are automated waterborne cleaning equipment primarily used for cleaning floating debris in rivers, lakes, and reservoirs. They can accurately identify and retrieve floating objects such as fallen leaves, plastic bottles, and aquatic plants, efficiently completing cleaning operations through a collection device. Traditional surface cleaning vessels use a net-based passive collection method, which suffers from low collection efficiency, reliance on manual intervention for cleaning, and cumbersome waste transportation.
[0003] Existing unmanned surface cleaning vessels improve operational efficiency by using conveyor belts for collection, but due to their heavy hulls, they consume a lot of energy. Meanwhile, the open-type passive waste collection is inefficient, and the collected waste can escape from the front when the vessel stops or reverses. Furthermore, conventional waste collection compartments are mostly one-piece metal frames, which cannot achieve lifting and draining functions. In order to meet the collection volume and hoisting requirements, a frame structure is required, which makes the frame heavy and results in a high moisture content in the transported waste. Utility Model Content
[0004] The purpose of this utility model is to provide a floating debris collection and storage device for unmanned surface cleaning boats in order to solve the above problems.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution, including:

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0032] Example 1:
[0033] like Figures 1-6 As shown, in one embodiment, a floating debris collection and storage device for an unmanned surface cleaning vessel includes a hull 1.
[0034] The hull 1 is made of aluminum alloy, which has lightweight characteristics to reduce the energy consumption of the hull 1 during navigation, and also has excellent corrosion resistance, which can adapt to long-term water operation environment. At the same time, the front of the hull 1 adopts an inclined angle design, which effectively reduces the impact of water flow on the hull 1 during navigation through the streamlined structure, thereby significantly reducing water flow resistance and improving the navigation efficiency and stability of the unmanned vessel.
[0035] For example, a collection device 2 is provided at the end of the hull 1. The collection device 2 includes a flow guide arm 202 and an elastic guide wheel 201. The collection device 2 is used to collect floating garbage.
[0036] Specifically, the flow guide arms 202 are symmetrically installed on both sides of the end of the hull 1. They adopt a V-shaped hollow flow guide arm with a diameter of 10mm×15mm. This can effectively filter out small and useless impurities, and with the guiding effect of the V-shaped structure, it can stably guide the dispersed floating objects to the collection area in the center of the hull 1. Correspondingly, the elastic guide wheel 201 is installed on the top edge of the outer side of the flow guide arm 202. It can play a buffering and protective role when encountering obstacles, and prevent the arm from being damaged by collision with hard objects.
[0037] Furthermore, a storage device 3 is provided in the middle of the hull 1. The storage device 3 includes an outer collection frame 302 and an inner collection frame 8. The inner collection frame 8 is installed inside the outer collection frame 302 and is used to store the collected garbage.
[0038] For example, the outer frame 302 is made of aluminum alloy with a 5mm aperture, which ensures the structural strength and corrosion resistance of the outer frame and facilitates drainage of the frame; the inner frame 8 is made of a detachable lightweight collection frame with a 3mm aperture, which ensures the overall strength of the frame and the weight requirements, while preventing deformation when the electric push rod lifts the frame.
[0039] It should be noted that a support frame 303 is installed on the outside of the collection frame 302, which is connected to the frame through a multi-point fixing method, effectively dispersing the force on the frame and improving its resistance to deformation; while a limit hole 304 is provided at the top edge of the collection frame 302, which can limit the lateral displacement, so that the collection frame 302 can only be raised and lowered in the vertical direction, avoiding swaying and deviation during the raising and lowering process.
[0040] For example, the inner frame 8 is hollowed out on all four sides, which can quickly drain water during waste storage and reduce the weight during transportation; and it is provided with a front plate 801, which can be rotated to open and close the inner frame 8.
[0041] Specifically, the front panel 801 and the inner collection frame 8 can be rotatably connected by a hinge, and the flip angle of the front panel 801 is 0-90°. When garbage collection is carried out, the front panel 801 flips to the 90° open state to provide a smooth passage for garbage to enter the inner frame; when garbage needs to be transferred, the front panel 801 flips to the 0° closed state to prevent garbage from falling during the transfer process.
[0042] In addition, a handle 802 is provided at the top edge of the inner collection frame 8 to facilitate the transfer of garbage after it is full.
[0043] It should be explained in detail that linear push rods 7 are installed on both sides of the bottom of the collection frame 302. The linear push rods 7 are symmetrically installed on the hull 1. The push rods meet the IP68 waterproof standard and can maintain stable operation in long-term underwater operation environment, avoiding failure due to water ingress. During operation, the electric push rods descend, lowering the bottom of the collection frame 302 to a position below the water surface. When the unmanned vessel is carrying out garbage collection operations, the electric push rods extend downward, lowering the bottom of the collection frame 302 to an appropriate position below the water surface, making it easier for garbage to enter the frame. After the operation is completed, the electric push rods retract upward, raising the bottom of the collection frame 302 above the water surface, realizing the dehydration of the frame.
[0044] Understandably, the storage device 3 consists of an outer collection frame 302 and an inner collection frame 8. The outer collection frame 302 is raised and lowered by a linear push rod 7 to naturally drain the water from the garbage, effectively reducing the weight of the garbage during transportation and saving transportation energy. At the same time, the inner collection frame 8 adopts a hollow, lightweight, modular structure and is equipped with a transfer hoisting handle 802 on the top, which facilitates the transfer of garbage after it is full, reducing the intensity of manual operation.
[0045] Furthermore, the inner frame 8 can be rotated open to open the front panel 801 during use and rotated closed during transport, which facilitates modular installation, replacement and transport of the inner frame 8. When an inner frame is full, it can be quickly replaced to continue operation, effectively shortening the operation interruption time and reducing the overall transport cost.
[0046] It should be noted that a rotating paddle assembly 301 is also provided at the end of the collection frame 302. The rotating paddle assembly 301 includes a paddle 3015, which is connected to a drive motor 3013 and is used to push the waste into the storage device 3.
[0047] Specifically, the actuating paddle 3015 is inserted into the rotating shaft 3014, and the actuating paddle 3015 is rotatably connected to the output end of the drive motor 3013 through the rotating shaft 3014; correspondingly, the output end of the drive motor 3013 is equipped with a bearing 3012, and the drive motor 3013 is rotatably connected to the bearing seat 3011 through the bearing 3012. The bearing seat 3011 is installed on the inner wall of the collection frame 302, ensuring the stability and structural strength during the rotation process.
[0048] For example, the pusher paddle 3015 adopts a stainless steel semi-hollow three-blade paddle design, with the paddle blades inserted on a solid stainless steel rotating shaft 3014. The overall structure takes into account both strength and lightweight. At the same time, it is mounted on an aluminum alloy bearing seat 3011 through a stainless steel bearing 3012. All metal parts are treated with anti-corrosion measures and are powered by a waterproof drive motor 3013.
[0049] Specifically, the speed of the drive motor 3013 is adjustable from 0 to 200 rpm. During operation, the speed can be flexibly adjusted according to the amount of debris on the water surface: when there is more debris, the speed is increased to enhance the vortex suction force, and when there is less debris, the speed is reduced to save energy. The structural design of the propeller 3015 is particularly ingenious. The side near the shaft 3014 uses a solid plate to ensure the strength of the blade, while the side away from the shaft 3014 uses a hollow plate to reduce water flow resistance, thus reducing rotational energy consumption while ensuring propeller efficiency.
[0050] Understandably, by driving the motor 3013 to continuously rotate the paddle 3015, a stable vortex can be formed in the collection area, actively pushing floating objects into the collection frame 302. This continuous flow generation effectively expands the collection range and improves the efficiency of garbage collection. At the same time, in the working state, the bottom of the paddle blade always remains at a certain depth below the water surface, forming a physical barrier that can effectively prevent the backflow of garbage that has entered the collection area. Even when the unmanned boat stops or reverses to adjust its position, the garbage will not escape from the storage device 3.
[0051] Example 2
[0052] Please continue reading. Figures 1-6 Based on Embodiment 1, in order to realize the autonomous navigation function of the unmanned vessel, a power unit 4 is installed at the bottom of the hull 1; for example, the power unit 4 typically includes a thruster and a drive motor 3013, and the thrust output by the power unit 4 drives the hull 1 to navigate on the water surface.
[0053] Correspondingly, the top of the hull 1 integrates a detection and monitoring device 5 and a navigation and positioning device 6. For example, the detection and monitoring device 5 includes components such as a high-definition camera, radar (e.g., millimeter-wave radar and lidar) and infrared sensors, which can identify obstacles and garbage distribution on the water surface in real time, enabling autonomous navigation and intelligent obstacle avoidance of the unmanned surface cleaning vessel. The navigation and positioning device 6 adopts GPS and Beidou dual-mode positioning technology, combined with electronic maps to achieve accurate positioning and path planning of the unmanned vessel, ensuring full coverage of the work area without omissions.
[0054] Working principle:
[0055] Start-up phase: The electric push rod (set stroke of 0-500mm) precisely lowers the bottom of the collection frame 302 to a depth of 200mm below the water surface. This depth ensures that the garbage can enter the frame smoothly, while avoiding excessive sinking of the frame and increasing navigation resistance. Then, the drive motor 3013 (initial set speed of 30r / min) starts, driving the rotating paddle to slowly rotate and form a stable vortex. The water flow suction force is used to attract surrounding floating objects to the collection area.
[0056] Collection stage: The inner collection frame 8 inside the outer collection frame 302 can adopt a double-layer filter structure. The outer layer is a stainless steel mesh (pore size φ3mm) to block larger waste, and the inner layer is a polypropylene folding basket (maximum load capacity 25kg) to collect small waste. Double protection ensures that no waste is missed during collection. The front panel 801 of the inner frame can be opened 90° by hinge, providing a wide passage for waste to enter, while the hollow structure continuously drains water.
[0057] Transfer Phase: The entire process is intelligently controlled by a PLC control system. The load weight is detected in real time by a pressure sensor installed at the bottom of the inner collection frame 8. When the weight of the garbage reaches a preset threshold (e.g., exceeding 20kg), the system automatically triggers the transfer procedure: the drive motor 3013 is immediately de-energized, the paddle 3015 stops rotating to prevent new garbage from entering; the buzzer sounds an alarm, and at the same time, the transfer signal is sent to the monitoring platform (mobile APP or computer client) via the wireless communication module to notify the operator to handle the situation; the front plate 801 of the inner collection frame 8 automatically rotates and closes to prevent garbage from falling; the electric push rod is raised at a steady speed of 5mm / s, so that the bottom of the outer collection frame 302 is completely removed from the water surface. After the garbage has naturally drained, the inner collection frame 8 is lifted off the ground by the top handle 802 for garbage unloading.
[0058] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
